Shill this!

We create clean, fair, fun games and projects for us and the degen community!


Gemcore is not what you think. Well I don't know what you think! Liquidity will be locked soon after listing.

10000 totalSupply
10% team (team NEVER sells all tokens in one shot. Several partial sells, and yes, sometimes the team loses. 
That's life, win some, lose some. We live and we learn.)

DYOR - Do your own research

be fast

don't be greedy

Don't cry if you lose. Wait for next angel round and try to make your money back...don't forget to learn! 

Not financial advice...

Degen means degenerate 

Good luck.
